Zusammenfassung:The nanogenerator is a device that can effectively convert the extra mechanical energy released by the environment or the human body into electrical energy. The device collects energy from the environment, such as wind, sound, and small mechanical energy, efficiently and with a low threshold. Because of their unique advantages and excellent output performance, nanogenerators have received wide attention in the field of energy harvesting. Coupled with its high flexibility, low power consumption, and the need for external energy storage devices to achieve complete self-powered characteristics, nanogenerators in other fields, such as acoustics, have high research and application value. The nanogenerators can not only greatly improve the flexibility, portability, and efficiency of the acoustic devices but also act as acoustic devices such as microphones and speakers. The structure and working principle of the triboelectric nanogenerators, piezoelectric nanogenerators, and pyroelectric nanogenerators and the successful combination of various nanogenerators with acoustic devices are reviewed. The feasibility of the application of the nanogenerator technology in the field of acoustics and the flexibility of the combination of nanogenerators and acoustic equipment are described, and the advantages of the equipment produced in combination of the two fields are briefly introduced. Finally, the development prospect and challenges of the nanogenerators in the field of acoustics are discussed, and personal suggestions are put forward.
